I have been watching some Fred Picker Z VI videos and noticed he uses a viewing filter to see contrast with adjacent tones.
Being red/green color-blind, I do sometimes struggle especially if items close to one another are similar in tone. I know Ansel Adams used a Wratten #90 and that Fred Picker did at one point sell a Zone VI filer, both which I have looked on eBay for some time with no success here in the UK.
I was wondering if anyone has the Stearman press ZoneView viewing filter and what their thoughts are please.
